Assessment of Salivary Gland Dysfunction after Radioiodine Therapy for Thyroid Carcinoma Using Non-Contrast-Enhanced CT: The Significance of Changes in Volume and Attenuation of the Glands

摘要

Although radiation induced damage to the salivary gland is a known complication of radioactive iodine (131I) therapy for thyroid carcinoma, prediction of the severity and reversibility of sialoadenitis is difficult. Our aim was to correlate the extent of salivary dysfunction assessed by salivary gland scintigraphy with changes in the volume and attenuation of salivary glands on nonenhanced CT in postoperative patients with thyroid cancer treated with RIT.
